..25 Referrinfr to the drawines Vand aarticularly to Figs. 1, 2 and 3, I show a machine in which a base 1 supports an upright 2, preferably made tubular and containing another upright member 3 also preferably made tub- 30 ular, the member 3 extending up beyond the upper end'of member 2.

Member 2 carries vat its upper end a heating element 5 conveniently circular in form, but with a segment cutoff, as shown in Fig. 3. rfhis heating element is preferably made of a series of parts or sections of coiled electrical resistance wire which lfurnishes heat by the passage of an electric current. Another heating element 6 is arranged above heating element 5 and secured to and supported by the latter by means of'uprights 7 7. Element 6 is preferably made just as element 5 is, and is conveniently provided with a central aperture having a collar 9 to permit it te be held in place by the upper end of tubular member 3.

Tubular member 3 carries a holder 10 for the articles to be toasted or heated or otherwise treated. This element -10 is preferably ac, in circular form, as shown in Fig.l2, and may be provided with a series of recesses or depressions 11-11 adapted to form seats or cup-like meinbersfor biscuit, sandwiches, or thelile Element 3 is arranged for rotation so that Athe articles of food which itcarries` may be moved around with it, a simple arrangement being to provide lower end of element 3' with a gear connection by means of pinions 12 and 13 with Va rotary shaft 111, which latter is connectedv by4 worm wheel 15- and worm 16 with electric driving motor 17. AQ clutch 18 having a handle 19 is arranged to make connection so that element 3 may be driven by motor 17 or-may remain stationary,

as desired.

4In usineA the device the sandwiches or biscuit or other articles of food, as desired, are placed on carrier 10 and the latter rotated so that .the articles of food will move from the front where they are placed and where carrierf 10 is uncovered by reason of cut-away portionin heating elements 5 and 6, to the rear Vof the machine where said articles are heated or toasted by the heating elements arranged above and below-them. Thus the f varticlesmay be put on and then carried around in the machine and when they come again to the front they are toasted or properly heated and may be removed to be served and eaten.

A switch 1()a is preferably placed in the circuit 10b so that said circuit may be opened and closedto causethe heating; elements 5 and 6 to operate or not. i

As ay preferred larrangement a projection 10c isplaced on the rotary lmember 10 and arranged to actuate said switch 10a so as to open the circuit 107 and throw .the heating devices 5 and 6 out of operation. By means of switchV 102*` this will be done l'automatically when member 1() is so rotated as to cause member 10c tostrilre switch 10a.

Preferably member 1()c is jointed or hinged so vthat it may be thrown into position indicated in dotted lines in Fig. 1, in which position it will not strike switch 10a. Thus rotation of member 10 maybe continued as long as [desired with heating devices operated, but bymoving member 1()c the same may be brought in position to strike switch 10n and open circuit and thereby render heating dcvices inoperative and soprevent burning or overheating of the food articles.

Referring to Fig. 4, the food carrying element or holder 10 is similarly mounted on a rotary upright tubular member 3 and the heating elements 5 and 6 are mounted on tubular upright 2 as before, but this latter member 2 is also rotated so as to rotate heating elements 5 and 6. This rotation .may be accomplished by providing member 2 also with gearing todrive it from shaft 14 as by means of pinion 22 and gear 23. The gearing ratio is such that food carrier and heating elements 5r and 6 will be moved to the back of the machine and then out again before the heating elements have completed VVtheir rotation.

In Figs. 'and 6 I show further modification in which the food carrier is in the form of a traveling belt 25 provifde'd'with cross slats or beams 26-26 to engage the articles of food and move them along. lThis belt 25 may be mounted on toothed Wheels 28 and 29 and the latter driven by a suitable motor or driving connection. The heating elements 30 and 31 are shown, respectively above and below belt 25 so that as the latter is moved along the articles maybe heated or toasted.

In this form of device the articles will be placed upon the traveling belt 25 before it enters the heating chamber or compartment and then they will emerge from the other end of said compartment and may be taken off `or will be dumped off on to a tray or platform as the belt moves downwardly along the periphery of the other supporting gear Wheel.

In all forms of the machine the exposed part of the food carrying element may be seen and will attract attention, so that the machine will serve also as a display or advertising device. l

It will be understood that changes and modiications may be made Without departing from the spirit of the invention.

IN hat I claim is 1. A machine of the class specified comprising an upright rotaryV member carrying near its upper end a radially arranged food holding member and a heating element arranged above the food holding member, and a tubular member arranged outside of said 'rotary member and carrying a heating element arranged below the food carrying member.

2. A machineof the class specified comprising an upright rotary member carrying near its upper end a radially arranged food holding member and a heating element arranged above th'e food holding member, a tubular member arranged outside of said rotary member and carrying a heating element arranged below the food carrying member, means for driving said rotary upright member, and a clutch device for throwing the driving mechanism into and out of operative relation.

3. A machine ofthe class specified comprising an upright rotary member carrying' said rotary member and provided at its up-` per end with a heating element. v

5. A device of the yclass specified having a rotary member carrying a rotary holder and al stationary tubular member enclosing lsaid rotary member and provided at its upper end with a heating element and an upper heating element arranged above the rotary holder and supporting means extending upwardly from the lower heating element so as to support `the upper heating element.

In witness whereof, I hereunto subscribe my name this 1st day of October, A. 1).1925.

MONROE HARRISON.
